Amazon ECS API to fetch 1000 top selling books
I need the API to fetch the top selling books on Amazon. By default it only fetches the top 10 items, but I need more than 10, near about 1000 items content by using single

To get the 100 bestselling books you have to specify the
ItemPageparameter:http://ecs.amazonaws.com/onca/xml? Service=AWSECommerceService& AWSAccessKeyId=[AWS Access Key ID]& Operation=ItemSearch& BrowseNode=17& SearchIndex=Books& ItemPage=2 &Sort=salesrank &Timestamp=[YYYY-MM-DDThh:mm:ssZ] &Signature=[Request Signature]Problem: The maximum ItemPage number that can be returned is 10. So you cant get past 100 books.

here's how I do it - but it won't work for more than 100 items after the end of this month as Amazon are limiting ItemPage to 10.
rescheck = Amazon::Ecs.item_search("search term here", :response_group => 'Large', :country => 'uk') n=0 rescheck.total_pages.times do |n| n=n+1 if n <= rescheck.total_pages res = Amazon::Ecs.item_search("search term here", :response_group => 'Large', :item_page =>n, :country => 'uk') res.items.each do |item| asin = item.get('ASIN') title = item.get('ItemAttributes/Title') brand = item.get('ItemAttributes/Brand') #etc讨论(0) -
